HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 518, 302, 453 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 518, 302, 453 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 518, 302, 453 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 518, 302, 453 is 1.
HCF(518, 302, 453) = 1
HCF of 518, 302, 453 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 518, 302, 453 is 1.
Highest Common Factor of 518,302,453 is 1
Step 1: Since 518 > 302, we apply the division lemma to 518 and 302, to get
518 = 302 x 1 + 216
Step 2: Since the reminder 302 ≠ 0, we apply division lemma to 216 and 302, to get
302 = 216 x 1 + 86
Step 3: We consider the new divisor 216 and the new remainder 86, and apply the division lemma to get
216 = 86 x 2 + 44
We consider the new divisor 86 and the new remainder 44,and apply the division lemma to get
86 = 44 x 1 + 42
We consider the new divisor 44 and the new remainder 42,and apply the division lemma to get
44 = 42 x 1 + 2
We consider the new divisor 42 and the new remainder 2,and apply the division lemma to get
42 = 2 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 518 and 302 is 2
Notice that 2 = HCF(42,2) = HCF(44,42) = HCF(86,44) = HCF(216,86) = HCF(302,216) = HCF(518,302) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 453 > 2, we apply the division lemma to 453 and 2, to get
453 = 2 x 226 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 453 is 1
Notice that 1 = HCF(2,1) = HCF(453,2) .
